    <abstract>Data sets used to prepare Figures 2-10 in the Journal of the Ceramic Society of Japan article entitled &quot;Bond counting strategies in an oxygen centric perspective on the structure of oxide glasses.&quot; The data sets describe the structures of several oxide glasses and provide the results obtained from bond counting strategies for examining the connectivity and nature of the network forming motifs. It is noted that the oxygen packing fraction acts as a marker for structural change in network-forming oxides under high-pressure conditions.</abstract>
